[0023] See also Figures 1 to 4 The utility model provides a technical solution: a secondary support device for a mining dump truck, comprising a support 1, wherein the support 1 is provided with two groups, and the two groups of support 1 have the same structure and are symmetrically placed between the top of the dump truck beam and the bottom of the truck compartment;

[0024] The secondary support device for the lifting carriage can effectively prevent casualties caused by the accidental falling of the large carriage. Although the truck's built-in hydraulic lifting system has a check valve and original support pins, the installation of the secondary support device for the lifting carriage ensures greater safety and greatly improves operational safety.

[0025] The support 1 includes a support base 2 and a rotating support frame 3. The support base 2 is hollow in design. The rotating support frame 3 is rotatably connected to the top of the support base 2. The bottom of the support base 2 is fixed to the truck beam, and the top of the rotating support frame 3 is attached to the bottom of the truck compartment.

[0026] When in use, the truck compartment is first tilted upward from the truck beam through the built-in hydraulic lifting structure. After it is lifted to a certain height, the built-in support pins of the truck can limit and fix the truck compartment. At this time, two sets of supports 1 are placed on both sides of the top of the truck beam, and the supports 1 are clamped between the truck compartment and the truck beam to prevent the truck compartment from falling back during maintenance.

[0027] The support base 2 includes a manganese steel plate 21 and a connecting steel plate 22. The manganese steel plate 21 and the connecting steel plate 22 are each provided in two groups. The two groups of connecting steel plates 22 are respectively fixed between the two groups of manganese steel plates 21. The manganese steel plates 21 are designed to be narrow at the top and wide at the bottom, so that the two groups of manganese steel plates 21 and the two groups of connecting steel plates 22 are combined to form a prism-shaped support structure.

[0028] The rotating support frame 3 includes a rotating connector 31, a rotating shaft 32 and a U-shaped support plate 33. The rotating connector 31 is provided in two groups and is symmetrically arranged at both ends of the rotating shaft 32. The top ends of the two groups of rotating connectors 31 are fixedly connected to the U-shaped support plates 33. The rotating shaft 32 is rotatably connected between the two groups of manganese steel plates 21.

[0029] The two sets of rotating connectors 31 of the rotating support frame 3 are both located inside the two sets of manganese steel plates 21 of the supporting base 2, and the manganese steel plates 21 limit and fix the rotating connectors 31;

[0030] After the truck compartment is lifted up, there is a certain angle between it and the truck beam. At this time, the rotating support frame 3 can rotate according to the size of the angle to ensure that it fits the bottom of the truck compartment. The support base 2 is placed on the top of the truck beam. After the placement is completed, the support device 1 has a certain supporting effect.

[0031] When in use, the U-shaped support plate 33 fits in place with the bottom of the truck compartment, and the rotating connector 31 drives the U-shaped support plate 33 to rotate and adjust the angle by rotating the rotating shaft 32 in the manganese steel plate 21. The prism-shaped support base 2 has strong support and can enhance the overall structural strength.

[0032] The support 1 is welded with 10mm manganese steel plate into a triangular prism with a smooth bottom, and the top adopts a U-shaped support that can be flexibly rotated 90 degrees. When in use, no matter what type of vehicle, it is only necessary to place the support in the angle area between the longitudinal beam and the car body after completing the original one-time support. Two are placed at the same time in a group. Since the top U-shaped support is adjustable, it can meet various angles when the car body is lifted on site, and the support is firm and easy to carry and operate, which greatly saves resources and achieves reliable protection. It has been fully promoted and used.
